To all whom, it may concern:

Be it known that I, THOMAS ASHWORTH, machinist, a subject of the King of Great Britain, residing at Lynwood, Urmston, in the county of Lancaster, England, have invented certain new and useful Improvements in the Formation of Cops in Spinning and Doubling Machinery, of which the following is a specification.

In the specification of a former patent, No. 613,106, dated October 25,1898, spinning and doubling mechanism is described by which the spun fibrous yarn is wound into .cops, the cops being wound nose downward, either upon a bare spindle or on a thin tube placed upon such spindle. When winding the cops nose downward in this way, it is desirable that the part of the spindle on which the cop is wound should be made to taper slightly toward the top, so that the cop when completed may readily be dofied or slipped off endwise from the spindle. Consequently the cops which are formed have a tapering hole extending through them, the larger diameter of which is at their nose end. This has interfered with the cops being used for weft, as it was difficult to pass the tongue of the shuttle up through the narrow end of the hole at the base of the cop, it being necessary to place the cop onto the tongue in this way as the yarn has to be drawn off from the nose end.

The object of this invention is to remedy this defect and to make the hole to taper in the right direction at the base end of the cop. For this purpose I place onto the tapering point of the spindle a tube of paper or other suitable light material, which gradually increases in thickness from its lower to its upper end, so that its exterior forms an inverted cone and is brought to a fine edge at its lower end. Longitudinal slits are made in the tube extending upward for some distance from its lower or thin end to give it a certain amount of elasticity and enable it to grip the spindle with which it revolves while the cop is being wound upon it. In some cases also I place a thin tube of paper or other suitable light material around the exterior of the above tube, such thin tube being preferably coned both externally and internally to correspond with the exterior of the tube around which it is placed. As the cop is wound base upward the central hole which extends through it will at the base end of the cop conform to the coned surface of the tube which surrounds the upper end of the spindle, so that this portion of the hole then tapers in the right direction to allow of a tongue or skewer being passed into it from the base end. When the cop is doffed, the split conical tube can readily be withdrawn from it. The tube or tubes may be of any desired length. Usually it is desirable to make it somewhat less than half the length of the cop. The thin paper tube, if one has been used, may be allowed to remain within the cop.

My invention is illustrated in the drawings annexed.

Figure 1 is a vertical section of a tapering spindle passing up through a tubular-inverted flier and of a cop formed around the spindle.

Fig. 2 is a similar section of the spindle with the paper or other tubes upon its upper end. Figs/3 and 4 are exterior views of the two tubes. Fig. 5 is a vertical section of a cop after it has been dotted from the spindle.

In Fig. 1, a is the inverted tubular flier, driven continuously bya band passing around the wheel I). c is a tapering spindle which passes up through the tubular flier and which,

'as heretofore, has a constant rising-and-falling movement given to it in addition to a slow continuous upward movement and is revolved by the drag of the thread. (1 is a cop wound on the spindle nose downward. With a cop so formed the diameter of the hole which extends through it is smaller at the base to the nose end.

In Fig. 2, e is a tube of paper or other suitable light material placed onto the upper end of the spindle, this tube being in the form of an inverted cone, thin at its lower end and thick at its upper end. f is one of two longitudinal slits which are formed on opposite sides of the tube a to allow its lower end to be somewhat expanded when it is placed onto the spindle. g is a conical tube of uniform thickness placed around the exterior of the tube 6. When a cop is wound onto a spindle so surrounded by the tubes 6 and g, a cop h of the form shown in Fig. 5 is produced. When the cop is doffed,the tubes e and g come away with it, and the tube 6 can then readily be taken hold of by its projecting end and withdrawn, while the tube g may be allowed What I claim is-- to remain within the cop, as shown in Fig. 5. 1.
